Abstract: An extract of hyssop (Gratiola officinalis) is prepared by (1) lixiviating powdered hyssop plant with a solvent comprising MeOH, EtOH, n-PrOH or iso-PrOH optionally diluted with water and completely evaporating the solvent by distillation leaving as residue a crude extract I, (2) boiling crude extract I with a solvent which is an aromatic or a cyclic hydrocarbon or with a chlorinated solvent decanting the hot solution and removing the solvent e.g. by evaporation under vacuum, preferably at 80 DEG C., to give a purified extract II, and (3) dissolving the purified extract II in water, extracting the solution thus obtained with an alkanol having 4 or 5 carbon atoms or a dialkyl ketone having 4 to 6 carbon atoms, separating the aqueous phase and removing the solvent from the organic phase e.g. by azeotropic distillation to give the purified extract III.  The solvent used in step (2) is preferably benzene, toluene, a xylene, a petroleum fraction of b. pt. range 55 DEG -130 DEG C., methylene chloride, dichloroethylene, chloroform or trichloroethane.  The purified extract III can be dissolved in MeOH and precipitated by the gradual addition of ether to give a pulverulent purified extract.  The extract of hyssop possesses a strong laxative action and a small toxicity and is used for the medication of human beings in the form of tablets and pills (which may be sugarcoated), granules and capsules, containing 10 to 100 mg. of the extract per unit.  Other laxatives and spasmolytics may also be present in the compositions.

Abstract: 1445084 Flattening metal plate HUGH SMITH (GLASGOW) Ltd 15 Oct 1973 [24 Oct 1972] 48897/72 Heading B3E A plate leveller comprises first fixed rolls 3 and second rolls 4, 5, 6, being movable in response to an electrical signal proportional to plate thickness and assumed yield strength, and a detector 21 responsive to passage of the tail end of a plate to move the rolls 4, 5, 6 to ensure flatness of the tail end of the plate relative to the remainder. In the Figure, the rolls 4, 5, 6 are moved by rams 7, 8, 9, in response to thickness variations sensed by rolls 13, 14 urged towards each other hydraulically pneumatically. The thickness signal is sealed in accordance with assumed yield strength and used to position the rolls 4, 5, 6. When the plate trailing edge passes detector 21, the rolls are reset after a time delay depending on plate thickness and yield strength. When the trailing edge passes detector 20, the apparatus is reset to receive the next plate.

Abstract: 1475760 Apparatus for separating liquids SOC GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECHANIQUES ALSTHOM and TECHNISCHE MAATSCHAPPIJ BERGMANN NV 13 Nov 1974 [14 Nov 1973] 49045/74 Heading B1D Apparatus for gravity separation of two liquids comprises a vessel with a central cylindrical chamber 4 into which the liquid mixture flows down pipe 2, upper and lower chambers divided by frusto-conical concentric baffles 7, 16 and separated by gratings 10, 19 from cylindrico-conical chambers 9, 18, which in turn communicate with respective outlets 14, 23 for light and heavy liquids. The outlets lead to pumps, whose speeds are adapted to the proportions of the two liquids in the mixture, and may also have valves (not shown) controlled by probes 13, 22 which monitor the qualities of separated liquids in chambers 9, 18. As shown pipe 2 discharges into a space enclosed by blades 5 which induce a swirling motion to increase the path length of dispersed droplets in chamber 4 to enhance coalescence. The blades could be rotated by the flow or by an external mixture. Fig. 2 (not shown) illustrates a simple baffle (24) below pipe 2. The heavy and light liquids which are carried between baffles 7 and 16 coalesce there and flow back to chamber 4. Final separation occurs in chambers 9 and 18 from which small amounts of heavy and light liquids flow back at F3, F5.

Straps 53 anchored to the roller 25 and cloak 55 ensure rotation of the roller as the latter is raised and lowered by the diaphragm to maintain the suit pressure constant. The exhaust duct can be connected to suction, and the air circulated through the suit can be used for breathing and cooling purposes and for removing moisture and CO 2 . For negative internal pressures, a tension or leaf spring is used. In Fig. 2, blind 23 passes over roller 25 and is anchored to diaphragm 27 and the lower edge of mouth 19; wire spring 29 provides the closure bias. The blinds can be of neoprene-coated nylon and can be protected by a wire guard integral with stop plate 41. In other applications of the pressure regulator, a fixed loading pressure may be applied to diaphragm 27.

An object AA<SP>1</SP> is illuminated by a light beam and a telescope 3 is used to observe the position of a point in the object AA<SP>1</SP> and its image, formed by the mirror system, in the image BB<SP>1</SP>, the two points being caused to coincide by movement of the optical axis of the system. A polarizer 42 and two #/4 plates 40, 41 may be included in the system so that the direct beam from object AA<SP>1</SP> and the reflected one forming the virtual image AB<SP>1</SP> are polarized in perpendicular planes.

Abstract: 1494485 Testing electrical apparatus; measuring speed electrically SUN ELECTRIC AUSTRIA GmbH 26 Nov 1974 [26 Nov 1973] 51120/74 Headings G1N and G1U The generator-voltage regulator of a motor vehicle is tested by firstly measuring its output current at two rotary speeds while maintaining its output voltage constant at a level below the operating value of the regulator; secondly measuring its output voltage at a constant current and thirdly determining the minimum rotary speed of the generator at the onset of current flow, (zero-watt speed). The first and third tests determine correct operation of the generator, and the second test - carried out with the generator running at its normal speed e.g. 6000 r.p.m. - monitors the voltage regulator operation. In measuring the zero-watt speed a tachogenerator attached to the generator driveshaft provides an alternating voltage proportional to speed which is rectified 31 or alternatively the tachogenerator provides a D. C. output and either is applied via a voltage divider 33, 33a and diode 34 to a capacitor 35. While the generator is running and producing output current, a voltage is developed across resistor 11 in its output. This voltage (smoothed by network 45-47) holds Schmitt trigger T9, T10 on, discharging capacitor 35 to virtual ground via diode 39. When the current falls to zero, T10 turns off and capacitor 35 is charged to a value representing the instantaneous generator speed. Diode 39 is now reverse biased and diode 34 also becomes reverse biased as the generator speed falls lower. The voltage on the capacitor is read out on meter 37.
